If you want ScangearMP to appear in the Dash, you can create a .desktop file for it.
Copy the following into a text editor:
Comment=Cannon's scanner software
Save the file with filename scangearmp.desktop
To use the desktop file from the Dash you will need to copy it to /usr/share/applications for any user to be able to use it (you will need administrator permissions) or to ~/.local/share/applications (where ~ means your user directory) if you just want it to be available for one user.
